Claims.

This invention relates to article wrapping machines and while broadlyapplicable, is particularly concerned with the wrapping of cigars incellophane paper.

.It is among the objects of the present invention to provide an articlewrapping machine which will automatically carry on the entire wrappingoperation including the feeding of articles, the application of wrappingmaterial, the tucking or folding of the material about the article andthe discharge of the wrapped article.

Another object is to provide a Cellophane wrapping machine adapted toheat the Cellophane and thus by a simple pressing operation seal thematerial by simple adhesion between portions thereof and without the useof a gluing or sealing material.

Another object is to provide a wrapping machine including means forsupplying from a continuous roll supply of wrapping material, individualwrapping sheets of proper dimensions, and as required by the rate ofarticle feed.

Another object is to provide a wrapping machine particularly adapted forcooperation with a conventional cigar banding machine so that it may beformed as a portion thereof, may be actuated thereby and therewith, andmay partake of automatic control thereof.

Another object is to provide a wholly cooperated device coordinated witha ban-ding machine for synchronous operation therewith so that itswrapping operation will be timed to accommodate the entire output of abandingmachine.

Another object is to provide a wrapping machine which in itself iscoordinated and synchronized so that article feed, wrapper supply andfolding operation all follow in cooperative timed sequences to the endthat the various operations follow in automatic sequence and the machinefunctions as a unit.

Another object of the invention is to provide a wholly coordinated andcombined assembly by which the foregoing objects are carried out in anovel simple and improved manner and thereby increase the production andreduce the cost of wrapping the cigar.

Another important object is to provide a wrapping machine in which theentire operation is automatic and does not require the human handling ofthe articles and which thus greatly reduces the amount of manual laboror supervision required.

A further object of the invention is to provide a machine adapted to beused as an attachment to or in connection with banding machines such as,for example, that illustrated my Patent No. 1,261,832, dated April 9th,1918, in my copending application on Cigar banding machines, Serial No.37,464, filed June 16, 1925, or in my more recent application on Cigarbanding machines, Serial No. 492,437, filed October 31, 1930.

In this specification no detailed description of the operation of thebanding machine will be made, but reference may be had to my patent andcopending applications aforesaid for a more complete disclosure of theoperation of such banding machine.

Other more specific objects and advantages of the apparatus will appearas the nature of the improvements is better understood, the inventionconsisting substantially in the novel arrangement and corelation ofinstrumentalities herein fully described and illustrated in theaccompanying drawings wherein similar reference characters are used todescribe corresponding parts throughout the several views and thenfinally pointed out and specifically defined and indicated in theappended claims.

The chsclosure made the basis of exemplifying the present inventiveconcept suggests a practical embodiment thereof, but the invention isnot to be restricted to the exact details of this disclosure, and thelatter, therefore, is to be understood from an illustrative, rather thana restrictive, standpoint. It will be understood that the variousfeatures of the invention may be separately applicable despite theircooperation herein shown.

While the above statements set forth a few of the more general objectsof the invention, it will be understood that the invention concernsitself with other objects and advantages too numerous to mentionrelating to structural detail and interrelation and cooperation ofparts, by means of which the advantageous functions are achieved, amajor object being to provide an efiicient, rugged, durable, simple andautomatic machine particularly adapted to meet the demands of economicmanufacture and operation.

In the preferred embodiment of the device, the invention preferablyconsists of a table arranged as an extension of a cigar banding machinetable. A wrapping paper roll holder is mounted with the table and apaper moving carriage, preferably operated by the banding machine drive,periodically delivers individual sheets cut from the roll to thewrapping mechanism per se. This mechanism utilizes suction means in apart of its operation and provides a cigar moving means coordinated withthe paper supply so that the paper is laid over the cigar. The foldingis accomplished by the joint movement of the cigar and paper and certainfolding arms. Heating means may be applied with parts of the structureto self-seal wrapping paper of the heat responsive type such asCellophane. All of the moving parts of the assembly are operated eitherdirectly or indirectly from a single drive shaft which is particularlyadapted for driving connection with a banding machine, the structure ofwhich forms no part of the present invention. In addition to many uniqueand improved structural combinations and interrelations, the inventionis broadly directed to the composite assembly and cooperative drive ofparts by which a proper sequence of operation is maintained and a whollyautomatic continuously operating device results.

It will be understood that while the invention is illustrativelydisclosed as a cigar wrapping machine for conjoint operation by and witha banding machine and embodying specific novel combinations, theinvention is in no wise limited to the use or structure here shown, andthus numerous changes, modifications and the full use of equivalents maybe resorted to without departing from the spirit or scope of theinvention.

The inventive idea involved is capable of receiving a variety ofmechanical expressions, one of which for the purpose of illustration isshown in the drawings.

The preferred structural embodiment of the invention includes a tableI!) which may preferably be formed, as here illustrated, as a lonitudinal extension of the table II of a conventional cigar bandingmachine. Extending at right angles from the table In is a wrappingmaterial supply assembly generally indicated at S in Fig. 2. At thejunction of the assembly S and the table 10, there is mounted a wrapperassembly generally indicated at W. Both the wrapper assembly and thewrapping feed assembly are coordinately operated through driving meanshereinafter described in detail and indicated generally in Fig. 1. Thedriving means is preferably connected with the banding power mechanism Pso that wrapping operation may be coordinated with banding operation.(See Fig. l.) The banding assembly is shown at B and cigars are fed tothe Wrapper partly by their discharge from the banding assembly. Whilethe invention is shown in connection with a banding machine of improvedmodern design, it is obvious that it is in nowise limited to suchcombination and is in its broader aspects adapted for individual articlewrapping use or in combination with various other devices. The inventionis not concerned with nor limited to the combination illustrated.

Wrapping material feed The Cellophane or other wrapping material feedassembly S is best shown in Figs. 2 to 11 and consists of a tableextending at right angles from the table In and the mounting thereon ofthe assembly W. The table is formed of three parallel rails l2 (see Fig.11) to which the material is supplied from a roll or similar materialsupply 13. The roll is supported by brackets I 4 which are carried byside frames l5 and I6 of the table rails l2. As shown clearly in Fig.'7, the material M from the roll l3 preferably passes downwardly under atension roller I! which is mounted for free vertical gravitationalmovement in slots N3 of supporting arms l9 depending from the ends offrames l5 and I6. On the other side of the roller I! the material Mpasses up over an end roller 20 supported by the frames and thence undera guiding transverse bar 2| carrying outwardly extending guiding fingers22. Upon the roller 28 and from under the bar 2|, the material passes toa material moving carriage which periodically carries the materialforward to be cut and fed to the wrapper. The combination of roll I3 androllers I! and 20 will be seen to permit movement of the material, apull thereon by the carriage acting to raise roller I! and supplymaterial at an even tension controlled by the weight of roller ll. Thisact may be by a feeding of material from roll l3 or not, but in anyevent no sudden pull and resulting spin of the roll I3 is evoked and aconsequent smooth, even, yieldable tension is maintained on the materialat all times.

A further aid in giving the proper tension on the material at all timesis the lever 23 pivoted at 24 with the cord 6| attached at 62 passingaround grooves on both sides of the roller I? and clamped at the upperend to the chain 29. As the chain 29 pulls the cords 6| forward, theroller raises at an even rate of speed thereby limiting the amount ofmaterial that can be fed.

For periodically moving the material forward towards the wrapper deviceW in response to requirement of material thereby, a carriagereciprocating upon the table rails |2 is utilized, which rests upon therails l2 and lies under a conforming material supporting slotted plate46. As shown in Figs. 7, 9 and 11 the carriage consists of a transversebed 25 having a pair of depending lugs 26 which extend through the slotsbetween the table rails i2 and carry under guide plates 2? which areunited by a chain link 28 of a chain 26 by which the carriage is movedas here inafter described. Opposite the lugs 26 supports 36, integralwith them, extend upwardly through the slots of the bed 25 so as to beabout flush with its top. These supports cooperate with gripper lugs 3|loosely mounted upon a transverse rock shaft 32 carried over the bed andsupported through upwardly extending carriage side plates 36. Betweenthe lugs 3|, the shaft 32 has secured for movement therewith a gripperoperating arm 34 which carries a cross bar 35, the ends of which restupon the upper sides of the ends of the lugs 3 6. Thus upon movement ofthe shaft 32, the bar 35 presses down the lugs 3| to engage the materialM against the supports 36, thus to move the material with the carriage.Reverse movement of the shaft will release the material to permitindependent movement of the carriage. For controlling the shaft 32 toperiodically hold or release the material, a simple electromagnet 36 isprovided which is supported on one end of the side plates 33. Its pole,upon energization, attracts a keeper arm extension 31 of the shaft 32,the shaft being normally held up with the arm 34 by a spring 38. Theelectrical control of the magnet is coordinated with the carriagemovement as will be hereinafter described.

The drive for the carriage (see Figs. 3, and 11) is maintained from amain drive shaft ll the end of which carries a crank 42 which oscillatesa crank arm 43 through a lost motion joint 66 (see Fig. 19) of a segmentgear 44. The gear 44 meshes with a bevel gear 45 carried upon atransverse shaft 46 supported in the side frames l5 and i6. Centrally ofthe shaft 46 a chain sprocket 4! is mounted over which a chain 29operates, one of the links of which is the link 28. The opposite end ofthe chain 29 passes over a free sprocket 35. It will be observed thatthe arrangement is such that for each revolution of the shaft 4! itscrank 42 gives the arm 43 a complete cycle of oscillation, which in turnfirst moves the shaft 46 in one direction and then back. In this cyclebrief pauses at the dead center positions of the crank will result. Suchrotations of the shaft 46 reciprocate the top section of the chain 29,and by its attachment to the carriage by link 28, the carriage isreciprocated.

For controlling the magnet 36 in timed sequence with the carriagereciprocation so that the material will be gripped only on forwardmovement of the carriage, a circuit involving a rail 56 is used. Therail extends along the table l2 and the carriage carries a leaf contactfinger 5| which upon movement of the carriage rides upon the rail, thuscompleting a circuit to the magnet 36. The other terminal of the magnetcircuit is grounded while the source of potential (see Figs. 8 and hasone terminal leading to the rail 50 and the other terminal leading to acontact 52 carried by the opposite frame I6. The frame l6 also carries amovable contact leaf 53 which is normally out of contact with 52. At theend of the rearward travel of the carriage, the contact 53 is struck bya cam operated lever 56 which is pivoted at 55 (Fig. 10). The electricalcircuit is thus established and magnet energized and the materialgripped. The lever 54 has its upper end rocked to the left to force thecontact leaf 53 against contact 52 by a cam wheel 56 operating on itslower end. The cam Wheel 56 is mounted on the shaft 6| and thus itsaction is synchronized with the forward travel of the carriage. When theupper end of lever 54 moves to the left to establish contact, its upperend pin 51 rides under and lifts a pivoted material gripper bar 56pivoted to the table, thus making it temporarily inactive while thewrapping material travels. This gripper bar 58 otherwise, when notinterfered with, holds the material tightly while it is being cut andkeeps it in position while the carriage returns to fetch a new supply.

The cutter 6i is pivoted at 68 and has an extending end 69 which isnormally pressed down by a spring 16 which thus holds the knife up. Atthe end of the forward movement of the carriage, which brings forwardmaterial under the bar 56 and cutter 61, the cutter is moved, the bar 58moves down to hold the paper and a tappet H engages under the extension69 and moves up to pivotally move the knife down to cut the materialagainst the tension of spring ill. The tappet 1| is connected to apivoted bellcrank 12, provided with a cam roller 13 which is rocked bythe cam M, keyed or otherwise fixed upon shaft 4|.

Feed of cigars and wrappers to wrapper mechanism and cigar elevation Thewrapping material while being fed by the carriage is guided bylongitudinally extending side guides (see Figs. 7 and 8) and under across bar l6 the paper passes under guide clips 1'! from the knife 61 tobe received in a wrapping sheet pocket 86, from one edge of which thesheet 8| extends slightly to be moved with a cigar by suction of fingers82. (See Figs. 22 to 26.) Under the pocket 86 the cigars are fed from abanding machine in a parallel row, a spring restrainer 83 being utilizedto limit the movement from under the pocket of more than one cigar. Thefingers 82 are synchronously reciprocated by a rod M preferably drivenfrom the banding mechanism or from any other common power supply for theapparatus. The fingers 82 have a stepped construction including an uppersurface 85 upon which the sheet rests and which is apertured incommunication with a suction passage so that the fingers inreciprocation will pick up the sheet 8| and carry it forward at rightangles to its path of supply from the roll and over the elevatingfingers to be hereinafter described. Rearwardly of the surface 85, thefingers have a step 86 terminating in an apertured parallel surface 81upon which the cigars are delivered. When suction is applied through thefinger ducts 88, the sheet 8| as well as the end
